Conan O'Brien just Tweeted some big news, announcing: "The good news: I will be doing a show on TBS starting in November! The bad news: I'll be playing Rudy on the all new Cosby Show."

Fox was rumored to be the main contender in picking up the late night talk show host, and reportedly he only started talking to TBS just last week. In a statement O'Brien declared: ''In three months, I've gone from network television to Twitter to performing live in theaters, and now I'm headed to basic cable. My plan is working perfectly.'

The show will debut in November, airing Monday through Thursday each week at 11 p.m. EST—meaning his move to the network will relocate George Lopez's show to midnight. Lopez is being a good sport, and said, "I can't think of anything better than doing my show with Conan as my lead-in. It's the beginning of a new era in late-night comedy." But WWMWD?
